LOOP BUCKLE Filed June 28, 1929 JEEELIP EALIS auRy ATTy Patented Sept. 9, 1930 UNITED STATES PATENT OFFICE JESSUP SALISBURY, OF HAMDEN, CONNECTICUT, ASSIGNOR- TO THE AMERICAN BUCKLE COMPANY, OF WEST HAVEN, CONNECTICUT, A CORPORATION OI CONNECT- ICUT LOOP BUCKLE Application filed June 28,

This invention relates to loop buckles having fixed inturned prongs for a strap engagement, and a relative sliding bar carrying means for protecting the points of the prongs.

The objects of the invention are to provide an effective strap holding buckle of simple construction; and toy provide a reversible buckle having prongs and having means, operable by a taut strap threaded into the buckle, for protecting the prong points.

The character of the invention may be best understood by reference to one illustrative device embodying the invention and illustrated by the accompanying drawing in which the Figure 1 is an elevation of a loop buckle with prong points exposed; the Figure 2 is a similar elevation, but with prong points protected; the Figure 3 is a section taken on the dotted line 33 of the Figure 2 with a strap threaded therein; and the Figure 4 is a perspective view of a movable part.

1 The device, as illustrated, is a loop buckle preferably made of wire of which the middle portion is bent to form a button loop, and

the remaining end portions being bent in Y substantially rectangular form above the button loop and providing the buckle frame having the bar portions 1, the substantially parallel frame'ends 2 and 3, and the aligned arms 4 and 5, substantially parallel with the bar portions 1, the aligned arms 4 and 5 being provided with the inwardly turned and relatively spaced prongs 6 and 7, respectively, lying within the plane of the buckle frame and directed toward the button loop. A bar 8 with attaching ends 9 and 10 looped around the frame ends 2 and 3, respectively, is mounted upon the frame for a relative sliding movement. The bar 8 is provided with means for 9 covering, and thus protecting, the points of the prongs 6 and 7 when the bar is moved into contact therewith. This bar 8 provided with such prong protecting means furnishes the novelty of this invention and may be constructed in any desired form; for the invention is not limited to any specific form of construction and the details of the device may be varied to produce the novel features herein claimed and to advantageously combine the 0 same with other elements employed in con- 1929. Serial No. 374,391.

nection with buckles and loops on garment straps, or the like. As illustrated, however, the bar 8 is flattened throughout its substantial length and in a plane perpendicular to the plane of the buckle frame, as illustrated and claimed in Letters Patent issued to the applicant on May 28, 1929, Number 1,714,924, and in addition thereto the flattened surface of the bar 8 ,is provided with spaced cupped formations 11 and 12 for registration with the points of the prongs 6 and 7, respectively, as illustrated by the Figures 2 and 4, being thus adapted to cover and protect the points when moved into close contact therewith.

To thread the strap into the buckle the strap may be thrust sidewise down between and under both prongs 6 and 7 so that the strap lies flatly upon the sliding bar 8, the free end of the strap being passed from the front of the loop buckle therethrough to hang down behind the button loop portion of the device. Upon the tightening of the strap within the buckle the portion thereof looped around the bar 8 exerts an upward sliding tendency upon the sliding bar 8 to move and maintain the same in close contact with the prongs 6 and 7 which, having penetrated the strap, are covered by their respective cupped formations 11 and 12 provided by the bar 8 and which protect the prong points as illustrated by the Figure 3. To release the strap for adjustment from its holding engagement within the buckle, the device is bodily tipped outwardly from the top, the tipping movement releasing the strap from the prongs and forcing the sliding bar downwardly, thus giving the threaded strap a free running course through the buckle. The mere righting of the device and a taut strap will again engage the prongs with the strap and urge the sliding bar into protecting engagement with the prong points.

The loop buckle is reversible in that the elevation as illustrated by the Figure 1 is substantially identical with the reversed elevation thereof (not illustrated).

I claim:

1. A loop buckle comprising a button loop supporting a frame provided with a fixed inwardly directed prong, and a bar mounted 100 upon the frame for a relative sliding movement into and out of engagement with the prong, the sliding bar carrying means for covering the prong end.

2. A loop buckle comprising a button loop supporting a buckle frame provided with fixed prongs inwardly directed toward the supporting loop, and a bar mounted upon the frame for a relative sliding movement into and out of engagement with the prongs, the sliding bar carrying means for covering the prong ends.

3. A loop buckle comprising a piece f Wire I of which the middle portion is bent to form a button loop, and'the end portions are bent'to form a substantially I rectangular buckle frame, the wire extremities being bent in- Wardly within the frame and toward the loop, to form spaced prongs, and a wire bar having ends looped around parallel arms of the frame for a relative sliding movement toward and away from the prong points, the

sliding bar being provided with means for covering the prongpoints.

4. A loop buckle comprising a piece of wire of which the middle portion is bent to form a button loop, and the end portions are bent to form a substantially rectangular buckle frame, the wire extremities being bent inwardly'within the frame and toward the loop to form spaced prongs, and a wire bar having its endslooped around parallel arms of the frame for a relative sliding-movement to-- I -i ward and away fromtheprong points, the sliding bar being provided withmeans for protecting the prong. points.
